METAL ROLLER.

Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed August 23, 1910. Serial No. 578,520.

To all whom it may concern:

Be it known that I, AUGUST Gaoss, a citizen of the United States, andresident of Corona, in the county of Queens and State of New York, haveinvented certain new and useful Improvements in Metal Rollers, 'of whichthe following is a specification.

My invention relates to that class of rollers more particularly adaptedfor so called ofiice furniture cabinets in which record books are kept,the object being to produce rollers having strength, lightness andstability so that heavy books passing over them will not have theiredges injured, nor render the rollers inoperative.

In the accompanying drawing, Figure 1 is a side elevation of my improvedroller partly broken away; Fig. 2 is an end elevation of the cylinder,Fig. 3 is an end view of the cylinder with a cap inserted, and Fig. 4 isan end view of the complete roller.

Similar reference characters denote like parts in the several views.

The cylinder, 1, may be a tube of the desired length and diameter, andmade of steel, brass or any other suitable metal. An annular groove 2 isrolled in at a proper distance from each end to stiffen the metal and toafford an internal shoulder 2 against which the edge of the fiange'ofthe cap 3 rests when in place: the cap is slightly conoidal in shape thetruncated part extending into an integral projection 4: which acts as abearing or pivot upon which the roller revolves; a small hole, 5, may bepierced in the cap to permit any liquid to run out, in case the rolleris plated or otherwise finished in a solution. An annular flange, 3, eX-tends at an angle from the conoidal part and is of a diameter to fittightly. into the end of the cylinder.

Such being the construction, the operation is as follows :The cylinderis provided with the grooves-forming internal shouldersat each end by asuitable tool, the cap is inserted until the edge rests against theshoulder; the edge 1 of the cylinder is then rolled or otherwise turnedover the cap, considerable power being exerted to lay the edge downtightly. \Vhen both caps have been thus inserted and seated, the rolleris ready for polishing or any succession of desired finishes to suit,the holes in the caps permitting any solution to runout freely to avoidrust or otherwise affecting the interior of the roller.

The bearing extends out beyond the cap, so that the roller can revolvefreely in a journalnot shownwithout touching the supporting means andbeing hollow throughout it is light yet very strong owing to itsconstruction.

hat I claim is A metal roller comprising a cylinder provided near eachend with an internal shoulder, and a conoidal cap for each end of thecylinder, provided with an integral journal projection, and an annularflange, the latter adapted to bear against the shoulder, the end of thecylinder being clamped over the cap to hold the latter in place withinthe cylinder.

Signed at New York city in the county of New York and State of New Yorkthis 22d day of August A. D. 1910.
